Add custom macro for JetEngine. Example - get the current user property, such as ID, user_email, etc.

	 * macros_name() - sets human-readable macros name for UI

I tried to use a macro to retrieve the lastest featured post ID so I could exclude it in other queries on the blog page. I cannot get it to work though. Here is my code for the macros_callback. The macros_args just returns an empty array.

` public function macros_callback( $args = array() ) {

        $myargs = array(
            'posts_per_page' => 1,
            'post_type' => 'post',
            'tax_query' => array(
                array(
                    'taxonomy' => 'featured-post-tax',
                    'field'    => 'slug',
                    'terms'    => 'featured-post-slug',
                    ),
                ),
            );

        $my_query = new WP_Query( $myargs );
        while ($my_query->have_posts()) : $my_query->the_post();
            $exclude_post_id = get_the_ID();
        endwhile;

        wp_reset_query();

        return $exclude_post_id;

    }`
